Integration constraints
The FX3U-4AD-ADP: The adapter draws 15 mA from the 5 VDC internal PLC supply and requires an external 24 VDC supply (24 V +20%/-15%, 40 mA). Connection to an FX3S PLC requires the FX3S-CNV-ADP converter; for FX3G, the FX3G-CNV-ADP is needed. On FX3U and FX3UC-32MT-LT (-2) units, a function expansion board is mandatory. The adapter occupies zero I/O points on the PLC, so it does not reduce the available digital I/O count. Grounding must be Class D with a resistance of 100 Ω or less, using a dedicated or shared ground. The withstand voltage between all terminals and ground is 500 VAC for 1 minute; insulation resistance is 5 MΩ or more at 500 VDC. The adapter is rated for operation in atmospheres free of corrosive or flammable gases and conductive dust. Altitude must be 2000 m or less; it cannot be used in pressurized environments above atmospheric pressure.
Environmental and mechanical ratings
Operating ambient temperature is 0-55°C; storage temperature is -25-75°C. Relative humidity range is 5-95% RH, non-condensing. Vibration resistance when DIN-rail mounted: 10-57 Hz at 0.035 mm half-amplitude, and 57-150 Hz at 9.8 m/s² acceleration, 10 sweeps per axis. Shock resistance: 147 m/s² half-sine pulse for 11 ms, 3 times per axis. Noise immunity is tested to 1000 Vp-p, 1 µs width, 1 ns rise time, 30-100 Hz repetition.
